HyukjinKwon opened a new pull request, #57039:
URL: https://github.com/apache/spark/pull/57039
### What changes were proposed in this pull request?
This is a follow-up of #57037 (SPARK-57959). That PR added an explanatory
comment block to `MetricsFailureInjectionSuite`, and four of those comment
lines exceed the 100-character limit, breaking the `scalastyle` check on
`master`:
```
[error] .../MetricsFailureInjectionSuite.scala:348: File line length exceeds
100 characters
[error] .../MetricsFailureInjectionSuite.scala:349: File line length exceeds
100 characters
[error] .../MetricsFailureInjectionSuite.scala:352: File line length exceeds
100 characters
[error] .../MetricsFailureInjectionSuite.scala:353: File line length exceeds
100 characters
```
This PR reflows the comment block so every line fits within 100 characters.
No code or test logic is changed.
### Why are the changes needed?
To fix the broken `scalastyle` check on `master` (and
`branch-4.x`/`branch-4.2`, where the offending commit was also backported).
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
```
grep -nP '.{101,}'
sql/core/src/test/scala/org/apache/spark/sql/execution/metric/MetricsFailureInjectionSuite.scala
```
returns no matches. The change is comments-only.
### Was this patch authored or co-authored using generative AI tooling?
